[s-cars] Big brake upgrade help

[Serge Filanovsky]

Kevin,

I got the ECS Stage III, but other than the rotors, same kit as yourself. I
too installed mine at friends garage, there was plenty of debate on the
topic of flipping the crossover tubes with the bleeders. We ended up doing
the switch and it was the right decision. I would suspect that if the black
paint on the crossover fittings is undisturbed, you need to do the swap.
This are some pics of the final product with some pointers.

> 5) I bought a power bleeder and two liters of ATE super blue.  Is two
